The prompt
Design a parametric solid ARRI PL mount rear lens cap. Overall Dimensions: Cylindrical body with a maximum total height of 51 mm and an outer diameter of 62 mm. Interior Clearance: Deep internal cavity with a depth of 25 mm and a bore diameter of 48 mm to clear the protruding rear element of an Atlas anamorphic lens without making contact. Mount Interface: Standard ARRI PL mount twist-lock engagement ring at the opening, featuring 3 locking lugs set to standard PL flange geometry. Exterior: Vertical knurled grip ridges running around the outer wall for manual tightening, and a flat 2 mm thick back wall. Output: Clean, single-body watertight B-Rep solid model suitable for STEP export."
